SMC-IO Modules

IO card for SMC4-4-16A16B type four-axis controller.

Including an input (IN) adapter plate and an output (OUT) adapter plate,

Mainly used to connect the circuit and connecting the spindle frequency control circuit of

0-10V.

Pin Definitions

5V 输出：Controller internal 5V output, when using the total current must not exceed

500mA。

0-10V/PWM：Jumper selectable, PWM or 0-10V output.

12V 输入：To use the 0-10V output, must at this port connected the 12V power

supply.

When 12V power supply and controller share, just put 12V positive line connected to

this port.

When used alone, 12V power supply, 12V input port is connected to the positive

electrode, a negative level is connected to GND port.

SMC4-4-16A16B input port can be connected to a mechanical switch or

NPN type of sensor,Recommended use 5V NPN type sensors. Connection as shown

below. Limit, origin, and other input devices can be fast IO connection in this way..

SMC4-4-16A16B

Output port in the form of sink current form, the voltage can be 5-24V, 500mA

maximum per channel can sink current, it is recommended not to exceed the maximum

per channel 200mA. When connecting the output device to be noted that the current

output terminal of the connected load must not be greater than 500mA, but can not be

short-circuited, otherwise it will cause system damage. Output port can be connected
